I have huge regrets about every card I have sold but you also have to take in consideration that this is market with very little liquidity. So if you want to sell quicker the bid prices would be more accurate. If you want to sell quick in bulk probably less
But yeah for those prices it was a steal in hinsight...but the game was...well it was kind of shit when it released tbh and is far better now.
Looking forward to PVE
Yeah, was a risky investment back then but it paid off nicely so far!
